Title: Production of original black plate for ultra thin galvanized steel plate having excellent shape
Inventor: HAGA KATSUHIKO
IPC: C21D8/02
Filed: 1981-10-06
Abstract: PURPOSE:To obtain a titled black plate having excellent shapes at considerably reduce energy to be consumed in production by using continuously cast materials or capped steel materials and specifying the temp. of hot finish rolling in production stages and the thickness of hot rolled blank materials. CONSTITUTION:The continuously cast slab of the steel contg., by %, <=0.08C, <=0.03 Si, 0.12-0.30 Mn, <=0.030 P, <=0.030 S, <=0.06 Al, and the balance iron and unavoidable impurities and >=10 Mn/s is hot rolled. In this time, the finish rolling is completed at the Ar3 point -700 deg.C, then the steel plate is coiled at 600-450 deg.C to provide a hot rolled steel strip of 1.6-2.3mm. thickness. In succession, the steel strip is cold rolled after descaling by pickling or the like. Here, the limitation of C results in decreased yield strength of the hot rolled plate and improved cold rolling performance. Since this effect is observed in hot rolling below the Ar3 point, the upper limit of the hot rolling is set at the Ar3 point. The temp. for heating slabs is made lower than in the prior art and the thickness of the hot rolled strip is decreased. Thus the original unit of quantity of heating is reduced, and the cold rolling is accomplished in the good finish state advantageously in terms of energy and working efficiency.

Title: Detection switch
Inventor: ISHIKAWA NOBUHARU
IPC: G01V8/10
Filed: 1995-05-31
Abstract: PURPOSE: To provide a detection switch which can set the proper threshold value by setting both threshold ON and OFF levels and also setting the center value between both threshold levels at a level lower than the arithmetical mean value of input levels. CONSTITUTION: The geometrical mean value is set at a level lower than the arithmetical mean value of both input levels V1 and V2 as the virtual center value. This geometrical mean value is equivalent to the equal level ratios set between 0 level and the center value Vceng. Then both threshold value Vthon and Vthoff are set with margins of the same width to the value Vceng. Thereby, the center value set between ON and OFF levels of the threshold value for detection of an object is set at a level lower than the arithmetical mean value of input levels set in two teaching modes. As a result, the substantially equal margins are secured among the signals of such types that have the input level variances which are frequently proportional to the absolute value of these input levels. Thus the input level variances can be stably detected.

Abstract: PURPOSE: To reduce the power consumption for pumps by detecting the head and the total discharge of pumps and selecting such a number of pumps to be operated as consuming the least amount of power.  
     CONSTITUTION: A computing element 7 calculates the power consumption on the basis of a head H for operating pumps computed by a computing element 5 on the basic formula (head on discharge side) - (head on suction side) and also total discharge of all pumps Q detected by a discharge detector 6, and compares it with those power consumption with one additional and reduced number of pump respectively, before transmitting an operating pump number command N. Provided that P is the power consumption calculated on the basis of the number of pumps presently in operation, power consumption P' with one additional pump possessing the same head and discharge, and power consumption P" with one reduced pump are calculated. When P'<P, one pump is added, and when P"<P, one pump is reduced. Thus, the power consumption can be reduced by increasing or reducing the number of pumps so that a proper flow rate may be established in accordance with the head of pumps.

Abstract: PURPOSE:To increase memory cell capacity for reducing wiring resistance by extending a capacitor element from the area above a gate of a transfer gate transistor onto a neighboring word line and then making thicker the film thickness of the area for forming capacity element of a word wire than that of the word wire. CONSTITUTION:A memory cell is provided at the crossing between a word wire 4 and a bit wire 16 on the surface of an Si substrate 1. The cell is provided with a capacity element 21 and a transfer gate PET 22 which transfers signal between the capacity element 21 and the bit wire 16 according to the signal from the word wire 4. The word wire 4 functions as a gate electrode of the FET 22. The capacity element 21 is extended from the gate of the FET 22 to the word wire 4. Also, since the neighboring word wire 4 is of relatively large film thickness, large effective area can be secured at the stage difference pat. thus achieving a large effective area even if the formation area is small and a large electrostatic capacity. Also, since the film thickness of the word wire 4 is relatively large. sectional area can be made larger even if the word wire width is made narrower, thus reducing wiring resistance.
